SPECIFICATION forming part 0f Letters Paten?. N0. 382,511, dated May 8, 1888.

Application filed July 30, 1587. Serial No. 245,747. (No model.)

To all whom t may concern.- v

Be it known that I, JOHN V. B. CARTER, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New. York, have invented certain new and useful Improvements in Stoves, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain improvements in the draft and tlues of a stove; and it consists in the construction and arrangement hereinafter described, the novel -points of which are specified in the claims hereunto an` nexed.

inthe accompanying drawings representing my invention applied to a heating-stove, Figure 1 is a sectional side view on the line a: x, Fig. 2. Fig. 2 is a section on the line y y, Fig. 1, the parts each side of the line of section being indicated by dotted lines. Fig. 3 is a plan view of the bottom, looking down from line e z, Fig. 2. Fig. et is an elevation of the front draft. Fig. 5 is an inverted view of the same. Fig. 6 is asection on the line yy, Fig. 5. Fig. 7 is a section on the line a." as', Figs. t and 5.

My improvements are represented in the accompanying drawings, in which A is the body or case of al heating-stove, B is the basesection, D is the fire-pot, and E the ash-pit.

Over the front draft, F, of the stove are formed two openings through the bottomplate into the air-dues G G', which areV cast in the bottoni C and follow the contour of the front and sides, extending outward along the front each way from the middle, turning at or nearly at right angles at the corners, and being carried back to, or about to, the middle of the sides, where they are turned upward to make connection with the vertical passages H'H,"l in the sides of the basesection. These passages H H extend upward to the middle part of the basesection, where they open under the grate at a. The openings a may be expanded or made T-shaped, as'shown in Fig. 1, to afford freer access of the air to the grate. These openings are protected from falling coals and ashes by the ash-chute b extending over them.

The draft-box F has openings for the passage of air both in front and below, and is provided with a right-angled slide, c, to cover both sets of draft-openings. A pin or stud, d,

in the bottom of the draft-box F passes th rough a slot, e, to hold itin place and limit its motion. The openings g in the under side of the slide c are so proportioned that there always remains a slight passage, as illustratedin the drawings, where the slide is represented at its closed position, the draftopenings in front being fully closed, while those below are still slightly open. The object of this is to keep a the fire, for the purpose of affording a constant ventilation to the room in which my improved stove is placed.

The course of the air in passing through the stove is shown by the arrows on the various igures. Entering through the openings g on the under side of the draft-box F, the air passes through the yiiues G G in the bottom of the stove to the side iues, H H', up these flues and through the openings a to the lower side of the grate.

The products of combustion rising from the fire may bey carried to the smoke-nue in any preferred manner.

i vslight current of air always passing through The lon er arrows in Fig. 3 indicate the course of roducts in the base of the stove after having been carried down from the combustionchamber in customary manner.

It will be seen that they pass around the ends of partitions in the base in awell-known manner, and in so doing they have the effect to heat the base and also the incoming fresh air in the exteriorly adjacent airinlet dues G G, which latter iiues serve to obviate excessive heating' of the exterior of the base on the front thereof, with .which portion of the stove the feet or clothing are most liable to come in contact. Thus the air to support combustion is preheated by a construction which prevents objectionable heating of the front of the stovebase.

A suitable check-draft opening (indicated by the dotted lines i, Fig. 2,) may beprovided in the back ashpit wall establishing corn-- munication between the smoke-flue and the ash-pit. This opening is provided with a sliding damperf. A I claim 1. The combination, with the base of a baseheatingstove and with a conduit or chamber for products of combustion with the airinlet flues,

TOO

of the air-in1et chamber F, and airflues G G', extending along the front and side walls of the stove and between said walls and conduit, and the vertical tlues H H, arranged to deliver the air immediately below the grate, substantially as specied, whereby the exterior of the stovebase is kept comparatively cool and the air supply is warmed.

2. rlhe combination, withthe base of a baseA heating stove, of an air-inlet chamber provided with air-inlet openings ou its side and bottom, a suitable damper or slide provided with parts that entirely close the inlets at the side, and others that partially close those at the bottom when said damper is in its shut position, and air-fines 'extending from said chamber to the space beneath the grate.

3. The combination, with the base of the stove, having an air-inlet, of a damper for such inlet, the damper being of such size relative to the inlet that in its shut position it partially closes said inlet, and a check-draft opening, i, provided with damper f, substantially as set forth, whereby thestovc will always ventilate the room and may be made at will to ventilate it without passing air through the tire.

4. The combination, with the base of a stove, of an air-inlet, exterior front air-fines, G G', the adjacent interior conduit or chamber for products, and a fuelchamber in communica.- tion with said dues and also with the conduit, substantially as set forth, whereby air is preheated and excessive heating of the front of the base is obviated.

5. The combination, with the perforated bottom of the base of a stove, of the chamber F, secured under the bottom and having its nterior in communication with the perforations in the bottom, a damper for air-inlets in the chamber, dues G G', extending from the perforations in the bottom around the exterior of the front and sides of the base immediately above its bottom and adjacent to a conduit for products of combustion, and fines H H', extending to the space beneath the grate, substantially as set forth.
